Definition

Hyponatremia is a condition in which the level of sodium in the blood is too low. This occurs when there is an imbalance in the amount of water and sodium in the body—too little sodium for the amount of water present. As a result, water moves into the body’s cells causing them to swell. This condition may be serious. It requires care from your doctor.

There are different types of hyponatremia, each resulting in low sodium in the body:

Prevention

To help reduce your chance of getting hyponatremia, take these steps:

If participating in sports, drink only as much water or sports drinks as you need to quench your thirst. Sports drinks that provide electrolytes, such as sodium, may be helpful during endurance events.

Work with your doctor to effectively manage any conditions that you may have.
